STEAM-HEATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 404,419, dated June 4, 1889.

Application filed February 21, 1889. Serial No. 300,773. (No model.)

To all whom it may concern.-

Be it known that I, HERMAN A. KROES- OHELL, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Steam-Heating Devices, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to devices for heating houses by steam, and more particularly to the manner of connecting the radiators with the steam-supply pipes. I-Ieretofore, on account of the expansion and contraction of the Vertical pipes generally called risers, particularly in high buildings, the radiators secured upon the floor had to be placed some distance away from the vertical pipes, and had to be connected therewith by branch pipes of a sufficient length to afford spring or yield with the expansion and contraction of such vertical pipes, whereby, however, the strains to which these pipes were subjected caused frequent leakage and required constant repairs; and it is the object of this my invention to overcome these former difficulties; and it consists in rigidly connecting the radiators to the vertical pipes to be entirely supported thereby, instead of, as heretofore, being secured to and supported by the floors of the building in a manner that with the expansion of the vertical pipe the radiators will move with it, all as will be hereinafter more fully described and specifically claimed.

In the accompanying drawings, Figure 1 represents a section, showing two floors of a building with the vertical pipe and two radiators secured thereto; and Figs. 2 and 3 are sectional plans of the radiators, showing the manner of connecting the same to the vortical pipe.

Corresponding letters of reference in the several figures of the drawings designate like parts.

A denotes the vertical steam-pipe, which at the same time answers for the return to the steam-boiler of the water from condensation. This pipe A, extending from the basement to the uppermost story of the building, has above each floor rigidly connected a radiator B, supported either at its middle on a bracket 0 or at one end on a bracket cl, which brackets may be clamped or otherwise secured upon the pipe A, and coupled atits top by a transverse rod 2 or a longitudinal rod f, secured to a collar g, placed around pipe A and inserted between the radiator-pipes for securing the radiator by means of a washer-plate h and nut o'. I do not desire, however, to be re stricted to this particular manner of connecting the radiator to the vertical pipe, since other devices for connecting the same may be used equally well to accomplish the same object.

Through a branch pipe a and valve 1) the pipe A communicates with the radiator. It will be readily seen the radiators thus supported by or suspended to the vertical pipe will rise and fall with the expansion and contraction of such pipe, and will thus-be entirely clear of the floors of the building, which are thus better accessible for cleaning and scrubbing and for laying carpets, while at the same time the steam-pipes are not exposed to destructive strains and provide a more direct communication with the radiators without horizontal branches placed below the floors, that are often the cause of fire from spontaneous combustion.

That I claim is The combination, with a vertical stand-pipe extending from the basement through the several stories of the building, of a seriesof radiators, one for each story, rigidly secured to such stand-pipe to be entirely supported thereby, so as to move with such stand-pipe during expansion and contraction of the same, these radiators at the same time being connected with such stand-pipe for steam-circulation, all substantially as set forth, for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.

HERMAN A. KROESCHELL.
